Abstract
The utility model relates to a farm vehicle gearbox assembly, which is characterized in that three pairs of corresponding gears which can joggle each other are arranged on an input axis and a final axis on the gearbox, thus the speed ratio assign can be designed rationally according to the diesel engine performance to ensure the diesel engine drive performance exert normally. The utility model can let the farm vehicle transport as well as work in the field, thus enlarging the applicable range of the vehicle.
Description
Affiliated technical field
The utility model relates to the agricultural transportation vehicle transmission assembly.
Background technique
At present, the agricultural transportation vehicle gearbox of extensive use is four gears, is provided with three forward gearss and a reverse gear, also has the gearbox of small part to have four or five forward gearss and a reverse gear.These gearboxes or gear are few, two top gear is realized by the driven gear engagement on the small gear final stage axle on engagement of the final stage driving gear on the direct final stage axle of the small gear on the input shaft and the input shaft respectively, cause between each grade Speed Ratio Distribution unreasonable, influence the performance of diesel engine performance.
Summary of the invention
The purpose of this utility model is a kind of many gears of design, and Speed Ratio Distribution is reasonable, can give full play to the agricultural transportation vehicle transmission assembly of diesel engine performance.
The technical solution of the utility model be on the input shaft of gearbox and final stage axle, install three pairs can corresponding meshed gears, thereby can be according to the performance of diesel engine, their Speed Ratio Distribution of appropriate design is to guarantee the normal performance of diesel powered performance.Make agricultural transportation vehicle promptly can be used for forwarding, can carry out farm work again, enlarged the Applicable scope of transport vehicle.
If utilize technique scheme design 5+1 gearbox, can use input shaft, two, three and four axles of output shaft, the installation of its gear and cooperatively interact as follows: fixed gear is arranged on the input shaft successively, the third gear shifting slide gear, fourth gear, five grades of shifting slide gears, have successively on two with one on the gearwheel of the normal engagement of fixed gear, the second gear shifting slide gear, little shifting slide gear, the second gear driven gear that can mesh with the second gear shifting slide gear on two is arranged on three successively, small gear, the gearwheel that can mesh with the little shifting slide gear on two has on the final stage axle and the normal small gear that meshes of differential mechanism gearwheel, with three on the normal engagement of small gear and respectively can with three reverse gear driven gears of little shifting slide gear engagement on third gear shifting slide gear on the input shaft and two, the fourth gear driven gear that can mesh with the fourth gear shifting slide gear on the input shaft, five grades of driven gears that can mesh with five grades of shifting slide gears on the input shaft.Second gear shifting slide gear on third gear shifting slide gear in this structure on the input shaft and two can adopt same fork controls.Because the use of duplex shift fork can make full use of the gear box space, compact structure has reduced the gearbox volume, has improved intensity.
Be convenient and use that wherein two shifting slide gears on the above-mentioned input shaft are that four or five grades of shifting slide gears in the 5+1 gearbox can adopt duplicate gear.
Description of drawings
Fig. 1 is the embodiment's of the utility model 5+1 design structure unfolded drawing;
Embodiment
In the present embodiment, the agricultural transportation vehicle transmission assembly is by casing, input shaft 10, two 8, three 6, four 4 and differential assembly 1 and the composition of the gear on each, its structural feature is: an intrinsic fixed gear 11 and third gear shifting slide gear 12 is housed on the input shaft 10, four or five grades of double crosslinking sliding gears 16,17, be fixed with two gearwheels 9 on two 8 with the normal engagement of input shaft fixed gear, second gear shifting slide gear 7 and two little shifting slide gears 18, intrinsic three small gears 20 on three 6, can be meshed with second gear shifting slide gear 7 install second gear driven gear 5 and can be meshed with two little shifting slide gears 18 install three gearwheels 19, on four 6, be fixed with and four small gears 3 of differential mechanism gearwheel 2 normal engagements, install three reverse gear driven gears 20 with three small gears 19 are often nibbled, can with four or five grades of duplicate gears 16,17 be meshed install fourth gear driven gear 21 and install five grades of driven gears 22.Three shift forks also are housed on casing, and one of them middle-grade duplex shift fork 13 can be stirred third gear shifting slide gear 12 and can stir second gear shifting slide gear 7 again, and low-grade shift fork 15 is stirred two little shifting slide gears 18, and high-grade shift fork 14 is stirred four or five grades of duplicate gears 16,17.
The gear transmission route of each gear of the foregoing description is as follows:
I shelves: 19 → three small gears of 11 → two gearwheels of a fixed gear, 18 → three gearwheels of 9 → two little shifting slide gears, 20 → three reverse gear driven gears, 21 → fourth gear small gear, 3 → differential mechanism gearwheel 2;
II shelves: 5 → three small gears of 11 → two gearwheel 9 → second gears of fixed gear shifting slide gear, 7 → second gear driven gear, 20 → three reverse gear driven gears, 21 → fourth gear small gear, 3 → differential mechanism gearwheel 2;
III shelves: third gear shifting slide gear 12 → three reverse gear driven gears 21 → fourth gear small gear 3 → differential mechanism gearwheel 2;
IV shelves: the gear 16 → fourth gear driven gear 22 → fourth gear small gear 3 → differential mechanism gearwheel 2 in four or five grades of duplicate gears;
V shelves: 17 → five grades of driven gear 23 → fourth gear of gear small gear, the 3 → differential mechanism gearwheel 2 in four or five grades of duplicate gears;
R shelves: 9 → two little shifting slide gear 18 → three reverse gear driven gears 21 → fourth gear small gear 3 → differential mechanism gearwheels 2 of 11 → two gearwheels of a fixed gear.
